The WG9918530005 Radiator Inlet Hose is a vital component in the engine cooling system of SINOTRUK Sitrak heavy‑duty trucks. It transports hot coolant from the engine block to the radiator inlet, where it is cooled before returning to the engine. This continuous circulation maintains the engine at its optimal operating temperature, preventing overheating and ensuring reliable performance in all driving conditions. A degraded or leaking hose can cause coolant loss, engine overheating, and serious mechanical damage.
Manufactured from high‑grade EPDM rubber with aramid fibre reinforcement, the WG9918530005 hose offers excellent resistance to heat, coolant chemicals, and pressure cycling. Its multi‑layer construction ensures dimensional stability even at temperatures up to 150°C and pressures up to 2.5 bar. The precision‑moulded ends and factory‑installed spring‑loaded clamps provide a secure, leak‑free connection to the engine and radiator, eliminating the risk of coolant loss. This genuine OEM component is a direct replacement for the original factory hose, ensuring a perfect fit and restoring the cooling system’s full functionality.
A properly functioning radiator inlet hose is essential for maintaining engine temperature and preventing overheating. The WG9918530005 hose eliminates the risk of coolant leaks and flow restriction, ensuring that your SITRAK or HOWO truck operates reliably and efficiently in all driving conditions.
The WG9918530005 hose is constructed from premium EPDM rubber that withstands continuous operating temperatures up to 150°C, ensuring reliable performance in the hottest engine environments.
Embedded aramid fibres provide exceptional burst strength and resistance to pressure pulses, ensuring the hose maintains its shape and integrity under high coolant pressure.
The hose features precision‑moulded ends and is supplied with high‑quality spring‑loaded clamps, ensuring a secure, airtight seal that prevents coolant leaks and maintains optimal cooling system pressure.
Designed to match the exact dimensions and routing of the original factory hose, the WG9918530005 radiator inlet hose allows for a quick, straightforward installation with no modifications required.
Prevents Overheating: The WG9918530005 hose ensures a consistent flow of coolant to the radiator, preventing engine overheating and protecting critical components from thermal damage.

Compatible Models:
The WG9918530005 hose is a direct cross‑reference for multiple OEM part numbers, ensuring broad applicability across the SINOTRUK truck range. Always verify compatibility using your vehicle’s VIN or existing hose part number.
Installation Tips & Best Practices:
The WG9918530005 radiator inlet hose is produced using state‑of‑the‑art EPDM extrusion and aramid fibre braiding techniques. The EPDM rubber is specially formulated to provide exceptional resistance to heat, coolant chemicals, and ozone, while the aramid reinforcement layer delivers high burst strength and resistance to pressure pulsations. The hose is then moulded to the exact shape required for the specific vehicle application, ensuring a perfect fit without kinking or restriction.
Each WG9918530005 hose undergoes rigorous quality testing, including burst pressure tests (≥ 4 bar), thermal cycle tests, and leak tests under vacuum and pressure. The hose is also subjected to coolant immersion and ozone resistance tests to guarantee long‑term durability in real‑world operating conditions. The end connectors are precision‑moulded with integrated ribs to ensure secure clamping and prevent blow‑off.
The manufacturing process adheres to ISO 9001 and IATF 16949 standards, ensuring that every WG9918530005 hose meets SINOTRUK’s demanding quality requirements. This guarantees that you receive a component that performs exactly like the original factory‑fitted part, providing reliable coolant delivery for hundreds of thousands of kilometers.
The WG9918530005 Radiator Inlet Hose from SINOTRUK Sitrak is the definitive choice for fleet operators and owner‑drivers who demand uncompromising cooling system reliability, engine protection, and ease of maintenance. As a genuine OEM‑grade component, it guarantees a perfect fit, reliable performance, and peace of mind—backed by SINOTRUK’s engineering excellence and decades of experience in heavy commercial vehicle manufacturing.
